Description
Technical field
The utility model discloses a kind of twin cylinder petrol engine, belongs to motor vehicle gasoline machine class technical field.
Background technique
The petrol engine that the current mobility car is used, especially the petrol engine that uses for motorcycle, beach buggy, great majority are single cylinder petrol engine, the transmission power of this petrol engine is little, and some Motor Vehicle is to use double-cylinder gasoline engine, but adapted is the oil immersion friction plate clutch, this clutch uses in the oil immersion environment, with respect to not having oil, dry-type centrifugal formula bel-drivenn clutch, lack some advantage, it is low to be not easy to maintenance and transmission efficiency.
Summary of the invention
At the deficiencies in the prior art, the utility model provide a kind of use reliable, be convenient to keep in repair, operate steadily and environmental protection be applied in twin cylinder petrol engine on the mini motor vehicle, especially be installed on the beach buggy, have advantages such as center of gravity is low, vibrations are little, applicability is strong.
The utility model is achieved through the following technical solutions:
The utility model comprises petrol engine casing, a countercylinder and centrifugal clutch, and wherein, a described countercylinder and centrifugal clutch combine by casing.
The utility model also comprises gear-box, and a described countercylinder is cylinder I and cylinder II, and both are installed on the casing, and centrifugal clutch is installed on the casing of two cylinder one sides, and the gear in the output shaft of centrifugal clutch and the gear-box is connected.
Described centrifugal clutch comprises driving wheel, follower and is connected driving wheel and the belt of follower, tensioner dish and extruding disk are housed on the driving wheel, be provided with centrifugal pearl in the tensioner dish, there is friction wheel in the outside of follower, be provided with centrifugal friction block in the friction wheel, the gear in follower and the gear-box is connected.
Described centrifugal clutch is installed in the left side or the right side of a described countercylinder.
Described cylinder I and cylinder II are V shape or flat opposed formula or abreast-type and are positioned on the casing.
During the running of the utility model petrol engine, the motion of steam-cylinder piston bent axle drives the driving wheel rotation of clutch, thereby drives belt, and belt drives the follower rotation of clutch, thus the working gear of driven gear case, and gear operation drives wheel movement.This device is not worked in the oil immersion environment, helps environmental protection, and double-cylinder gasoline engine is mixed centrifugal clutch, has given play to more performance.
The utlity model has following advantage:
1, noise is little, use is reliable, be convenient to maintenance, user cost is low;
2, double-cylinder gasoline engine have operate steadily, power is big, transmission efficiency is high;
3, especially be installed on the beach buggy, have that center of gravity is low, vibrations are little, applicability is strong.
